Top 3 medical misconception.

The truth is, an amazing number of our ideas about health are misconceived or simply wrong. Here’s a handful that have turned out to be off the mark.

MYTH #1: “Overweight” Means “Unhealthy”

A debate has raged in medicine for years: Can you be fat and fit?

To a degree, this debate boils down to a numbers game. Many doctors use body mass index (BMI) to determine whether a patient’s weight is healthy or unhealthy. The BMI is a number that describes the ratio of your weight to your height. According to the Centers for Disease Control and Prevention, having a BMI under 25 means your weight is normal, 25 to 25.9 means you are overweight, and 30 or higher means you are obese. It’s clear, however, that this breakdown is oversimplified and in some cases inaccurate. For starters, many buff athletes with chiseled pecs and bulging biceps have high BMIs, since muscle weighs a lot.

While this study suggests that heavyweights can be healthy people, it’s important to keep in mind that lugging around a lot of abdominal fat does appear to be unhealthy. In fact, having a big belly increases the risk of heart disease and type 2 diabetes. (What’s big? For men, 40 inches or more; for women, 35 inches or more. To measure your waist, wrap a tape measure around your bare abdomen just above the hipbones so it’s snug but not tight. Inhale, exhale, and measure.) Fortunately, exercise burns belly flab, which is all the more reason to keep hitting the treadmill if you’re overweight.

MYTH #2: Your Fate Is Already Sealed

You often hear this kind of fatalistic remark from people whose parents died young of heart attacks or cancer: “What’s the point of jogging and eating broccoli if my lousy genes are going to kill me anyway?” Furthermore, each passing week seems to bring news that scientists have discovered yet another “disease gene.” If our health destinies are preprogrammed, does it really matter whether we take care of our bodies?

The same scenario seems to hold true for other diseases that can rob you of years. Imagine a pie chart representing all the factors that influence how long you will live. Many studies suggest that the genes you inherited from your parents make up only about one-third of the pie, and maybe less. The other items in the pie include diet, physical activity level, and personal habits, such as tobacco use and alcohol consumption. In other words, you can’t change your DNA, but what makes up the rest of the pie is largely up to you.

MYTH #3: Prescription Drugs Are Guaranteed Safe

It sure looks that way on the slick ads that fill the airwaves and magazines. As we noted earlier in this chapter, however, about 10 percent of prescription drugs that hit the market are later discovered to cause serious side effects that didn’t turn up in clinical trials. With that in mind, you might think that pharmaceutical companies would want to keep close track of whether people become ill when they take new drugs the companies market. In fact, the FDA requires them to do just that. Yet drug companies fail to perform these follow-up studies 70 percent of the time, says Paul Brown, a consumer health advocate with the US Public Interest Research Group.

That doesn’t mean new drugs have no value. If there are currently no medications available to treat your condition, and there’s solid evidence that a new medication is effective without causing intolerable side effects, the new drug could offer some hope. However, if a heavily hyped new drug would merely replace a medication that’s currently working well for you, then why switch and expose yourself to unknown risk? If your doctor recommends doing so, ask why.

Thankyou.
